Product Description
The WJA1021 is a cascadable gain block that offers high linearity in a low-cost surface-mount package. At 1.9 GHz, the WJA1021 typically provides 17.5 dB gain, +37.5 dBm OIP3, and +19 dBm P1dB. The device is housed in a lead free/green/RoHS-compliant industry-standard SOT-89 SMT package using a NiPdAu plating to eliminate the possibility of tin whiskering.
